Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, specifically to a fabric guiding device for textile machinery. Background Technology

[0002] The textile industry is the industrial sector that processes natural and chemical fibers into various yarns, silks, threads, tapes, fabrics, and their dyeing and finishing products.

[0003] The existing fabric conveying device clamps and fixes the two corners of one end of the fabric, unfolds the fabric and pulls it onto the conveyor belt, and then smooths the fabric laterally with a bidirectional threaded roller.

[0004] However, the existing technology lacks a longitudinal tensioning mechanism, which makes the fabric prone to longitudinal wrinkles during the conveying process. In order to solve the deficiency of the lack of a longitudinal tensioning mechanism in the existing technology, this application proposes to solve this problem by using components such as a rotating frame and a rotating arm. When the traction frame pulls the fabric, the return spring can push the slider to slide, so that the slider can drive the rotating frame to rotate through the connecting rod and the rotating arm. This allows the movable roller and the positioning roller to clamp the fabric, thereby making the fabric relatively tighter and improving the smoothing and wrinkle removal effect. Therefore, a new solution is needed to solve this problem. Utility Model Content

This utility model, by setting up components such as a drive rod and a pressure bar, and through the cooperation between the drive rod and the pressure bar, enables the drive rod to rotate and drive the pressure bar to slide, thereby causing the pressure bar to compress the auxiliary spring. This achieves the effect of adjusting the contact force between the movable roller and the positioning roller by setting up the drive rod and the pressure bar. Attached Figure Description

Each of the components is slidably connected to the outer surface of the corresponding slide bar 3. One end of each return spring 9 abuts against the outer surface of the corresponding slider 8, and the other end of each return spring 9 abuts against the outer surface of the conveyor table 2. The distance from the rotation axis of the rotating frame 4 to the axis of the movable roller 5 is equal to the distance from the rotation axis of the rotating frame 4 to the axis of the positioning roller 11. The two sides of the traction frame 12 are slidably connected to the two slide bars 3. Two pneumatic claws that can move in opposite directions are installed on the upper surface of the traction frame 12 for clamping and unfolding the two corners of the fabric. A drive screw is installed on the upper surface of the conveyor table 2 for driving the traction frame 12 and other components to move along the axis of the slide bar 3, thereby pulling and guiding the fabric onto the conveyor table 2. When the traction frame 12 moves to the side away from the positioning roller 11, the return spring 9 drives the rotating arm 6 and the rotating frame 4 to rotate through the slider 8 and the connecting rod 7, so that the movable roller 5 contacts the positioning roller 11.

[0026] A first motor is fixedly mounted on the outer surface of the bracket 10. Two first pulleys 13 are rotatably connected to the outer surface of the bracket 10. The output end of the first motor is fixedly connected to one end of the positioning roller 11. Each first pulley 13 is fixedly connected to both ends of the positioning roller 11. The rotation direction of the output end of the first motor is opposite to the rotation direction of the transmission roller of the conveyor table 2.

[0027] The support 10 is rotatably connected to a threaded roller 14. Two second pulleys 15 are rotatably connected to the outer surface of the support 10. The outer surface of the threaded roller 14 is provided with bidirectional threads. Each second pulley 15 is fixedly connected to one end of the threaded roller 14. Each second pulley 15 is connected to the first pulley 13 via a transmission belt. The threaded roller 14 applies lateral friction to both sides of the fabric by rotating, thereby enabling the fabric to unfold better.

[0028] A drive bar 16 is provided below the conveyor 2. A support rod 17 is rotatably connected to both ends of the drive bar 16. The other end of each support rod 17 is rotatably connected to the rotating frame 4. The drive bar 16 can drive the rotating frame 4 to rotate through the support rod 17.

[0029] Two support plates 18 are fixedly connected to the lower surface of the conveyor 2, and two support rods 19 are fixedly connected between the two support plates 18. The outer surface of each support rod 19 is slidably connected to the inside of the drive bar 16, and the support rod 19 plays a supporting and limiting role for the drive bar 16.

[0030] Two auxiliary springs 20 are provided on one side of the drive bar 16. One end of each auxiliary spring 20 is in contact with the outer surface of the drive bar 16. Each auxiliary spring 20 is sleeved on the outer surface of the corresponding support rod 19. Each auxiliary spring 20 can push the rotating frame 4 to rotate through the drive bar 16 and the support rod 17.

The outer surface of the drive rod 21 is threadedly connected to the inner surface of the pressure strip 22. The outer surface of the drive rod 21 is sleeved with the inner surface of the drive bar 16.

[0032] The implementation principle is as follows: The traction frame 12 is moved to a position close to the positioning roller 11. The traction frame 12 drives the rotating frame 4 to rotate via the slider 8 and connecting rod 7. The return spring 9 is compressed, placing the two front corners of the fabric into the pneumatic grippers of the traction frame 12. The grippers are activated to clamp and fix the fabric, sliding it to both sides to unfold the front end of the fabric. The traction frame 12 is then moved away from the positioning roller 11, guiding the fabric onto the conveyor table 2. The return spring 9 pushes the slider 8 to slide, and the slider 8 drives the rotating arm 6 and rotating frame 4 to rotate via the connecting rod 7. Simultaneously, the auxiliary... Spring 20 pushes drive bar 16 to slide, drive bar 16 pushes rotating frame 4 to rotate through support rod 17, so that movable roller 5 contacts positioning roller 11, clamping both sides of the fabric and making one side of the fabric contact the outer surface of threaded roller 14. Start the first motor, the output end of the first motor drives positioning roller 11 to rotate, positioning roller 11 drives threaded roller 14 to rotate through first pulley 13 and second pulley 15. Positioning roller 11 and movable roller 5 apply longitudinal friction force to the fabric, and threaded roller 14 applies transverse friction force to the fabric, thereby smoothing the fabric.
